LOVE IT! I have the response trigger with the cyclone feeder and it is so fast. not full auto though unless you hit the "sweet spot" on the trigger.The cyclone feeder feeds fast enough for my trigger.

I got this upgrade and tried to install it but to no avail, found out I had the older tippman 98. I got a newer tippman 98 and install was easy. I have yet to try it in action, I will update my review then, for now it gets five stars. To add about the older tippman, you can still upgrade with this feeder, you need to contact Tippmann directly per instructions in the cyclone kit, let them know your issue and they will ship you the internal part needed, "power tube", for FREE to complete your upgrade. Step by step Install directions for both can be found on YouTube, the power tube install is a complete dismantle of the tippman 98.

Bought this for my Project Salvo along with the response trigger and wow! They work awesome together! Easy installation and fast shipping. My old hopper is gravity fed and it was not keeping up with the rate of fire I was shooting, but this Cyclone Feed System has no problems at all even with the response trigger! All around a great product and I highly recommend this to anybody who wants a fast hopper that requires no batteries. Just make sure you buy the adapter kit if you are getting a response trigger because you need the banjo "T" fitting for both systems to work together. My Salvo is a beast now and everyone turns their heads when I fire it!

I didn't have to get the adapter for my 98 custom like some people had to, so the installation was pretty easy. I did have some trouble installing the connector tube that connects your CO2/HPA to the feeder. It felt like it was too short, but any longer and it would potentially get in the way.

On the field this thing performed flawlessly. I could fire as fast as I wanted and never worry about it not feeding. I have a stock 98 custom, so I don't know how it handles with a response trigger, but I don't think it should have any issues.

I highly recommend this as an upgrade to your feeder system

Five stars This hopper is an absolute beast! I bought the cyclone feed in the beging of august and replaced the original paddles with green squishy paddles very worth it .so far I've used it about it about 4 and have not had a single broken balls , consideringI've put about 3-4 thousand balls that's pretty impressive. Also significantly increases your bps. So if your looking for a great speed hopper ( not electric, its co2 based) for your Tippman with a significantly lower price tag then the dye rotor and other speed feeds on the market then this is the one for you. Don't hesitate I did and I regret not getting it earlier.
